I purchased a used Trophy from a Triumph dealer and have had problems with it from day one. The bike would not idle and stay started when cold, and once I got it to run it would sputter during acceleration as if it were going to stall. I took the bike back to the dealer twice and they alleged to have reset the idle and mixture settings yet the same problems persisted. So I took it back a third time and they are know saying that a spark plug was loose and there is fowling and the starter coil is shot. The kicker is they are trying to charge me for it when clearly to me it is is line with the problems I´ve experienced with the bike. Has anyone experienced anything like this with this bike?
